Aztec ATS430
Turbidity sensor
Introduction
The ATS430 sensor is a rugged, reliable instrument designed to measure
the turbidity and suspended solids content of water.
The sensor is designed for use with the ABB AWT440 multi-input
transmitter featuring EZLink connection. EZLink enables new or
replacement sensors to be easily connected without the need to power
down the transmitter.
